How to add demographics, places and environmental data to catchments

The Data tools add TravelTime Data API layers to your catchments, so you can see who lives within reach, what’s nearby and what the area is like.

The data layers

Layer	What it includes	Filters
Demographics	Population and demographic data	–
Places	Points of interest	Place group, then categories and sub-categories
Open spaces	Public open spaces	Green Spaces, Beaches, or both
Neighbourhood	Noise, air quality, flood risk, crime, deprivation and broadband	Any of the six measures

All filters are picked from lists. Leave a filter blank to include everything in that layer.

Two tools

Data from Locations starts from a point layer. It works out each location’s travel-time catchment for you, then returns the data inside it. Set the travel mode, whether journeys depart or arrive, the time period and the travel time, up to 180 minutes (90 at resolution 10). It uses the Core transport modes.

Data from H3 Cells starts from a layer of H3 cells you already have, such as the output of an H3 or Location Analytics tool. Set the Cell ID Field (h3_id in H3 tool outputs). For totals, set the Catchment ID Field (Index_id) to total each catchment separately, or leave it blank to total the whole layer.

Both tools are in the Data toolset of the TravelTime toolbox.

Data from Locations set up for Neighbourhood data per cell, within a 15-minute walk of each office

Three output types

Output type	What you get	Layers
Totals	One polygon per catchment, with the totals as fields	All
Per cell	One hexagon per H3 cell, with that cell’s values	All
Features	The individual places or open spaces, as points	Places and Open spaces

For Per cell, choose the resolution: 9 for Demographics and Neighbourhood, 6–10 for Places, and 9 or 10 for Open spaces.

A Totals output for five offices: population, residents, households, age shares, renters, car ownership and household income per catchment

The results are added to the map already styled. Each Neighbourhood measure gets its own layer, Places per cell is coloured by count, and Open spaces per cell shows which cells have green space.

Quick Data for a single location

For one address or point, use Quick Data in the TravelTime tab. It returns the data for one catchment and shows the results in a window. See How to use the quick tools in ArcGIS.

Things to know

Save the output to a file geodatabase. The styled layers only load from one.
Your IT team may need to allow https://data.traveltimeapp.com as well as the main API.
For Totals, a catchment can contain at most 200,000 cells, which a very long drive can go over. Shorten the travel time if this happens.
Data requests don’t count towards your Hits Per Minute limit.
